### Install MakeZero

Source: https://github.com/ashanbrown/makezero/blob/master/README.md

Install the makezero tool using the Go install command. Ensure you specify the version tag for the latest release.

```Go
go install github.com/ashanbrown/makezero/v2@latest
```

### Basic Slice Initialization with Append

Source: https://github.com/ashanbrown/makezero/blob/master/README.md

This example demonstrates a common scenario where a slice is initialized with a non-zero length and then appended to, which can lead to unintended empty elements. Makezero flags this pattern.

```Go
func copyNumbers(nums []int) []int {
  values := make([]int, len(nums)) // satisfy prealloc
  for _, n := range nums {
    values = append(values, n)
  }
  return values
}
```

--------------------------------

### Recommended Zero-Length Initialization

Source: https://github.com/ashanbrown/makezero/blob/master/README.md

This snippet shows the recommended way to initialize a slice when you intend to use `append`. It specifies an initial length of 0 and capacity based on the input slice length.

```Go
values := make([]int, 0, len(nums))
```

--------------------------------

### Slice Initialization with Index Assignment

Source: https://github.com/ashanbrown/makezero/blob/master/README.md

This Go code initializes a slice with a non-zero length and then assigns elements using an index. This pattern is discouraged by makezero when the slice is not intended to have pre-filled empty elements.

```Go
func copyNumbers(nums []int) []int {
  values := make([]int, len(nums))
  for i, n := range nums {
    values[i] = n
  }
  return values
}
```

--------------------------------

### Ignoring MakeZero Issues

Source: https://github.com/ashanbrown/makezero/blob/master/README.md

Use the `// nozero` directive as a comment on a specific line to ignore any issues reported by makezero for that line.

```Go
// nozero
```
